This is from a Norwegian based clothing brand called Kompis Clothing, inspired by the South Park episode of the same name. I’m actually wearing the shirt right now, in an office where at least 50% of the people are warcrack addicts The shirts are a bit pricey for people shopping from the US, but $5 of each sale does go to charities.

1$ goes to the environment organization Zero, 1$ goes to Amnesty International, 1$ goes to Psykisk Helse, 1$ goes to Save The Children/Redd Barna and 1$ goes to ØAs Stiftelse. This might seem to you as a marketing trick from our side, but we can ensure you that we’ve contacted all the organisations and they have approved that we can place a state in our webshop that we will donate the money to them.

As for copyright infringement, I don’t think the word “Warcraft” is copyrighted, nor the slogan “Make Love Not Warcraft”. The t-shirt is based on the South Park-episode with the same name (see http://www.youtube.com/watch?v=yoCN9YD6Ywo), and they also use episode names like “Lord of the Rings Pt. 1″ so I doubt their episode names are copyrighted.
